Hibiscus rosa-sinensis plant named &#39;island magic&#39;

ABSTRACT

A new and distinct cultivar of  Hibiscus  plant named ‘ISLAND MAGIC’, characterized by a large multicolored flower with a red center, radiating out to shades of orange-red with a yellow halo around the edges ‘ISLAND MAGIC’ is a free flowering plant with an upright, compact habit, and glossy, dark green foliage.

BOTANICAL CLASSIFICATION

Hibiscus rosa-sinensis ‘ISLAND MAGIC’.

VARIETAL DENOMINATION

The new plant has the varietal denomination ‘ISLAND MAGIC’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofHibiscus, botanically known as Hibiscus rosa-sinensis and hereinafterreferred to by the cultivar name ‘ISLAND MAGIC’.

The genus Hibiscus comprises about 250 species of herbs, shrubs andtrees in warm temperate and tropical regions; with leaves usuallysimple, mostly palmately veined, lobed or parted; flowers are mostlysolitary in the leaf axils but sometimes in racemes, corymbs orpanicles. Hibiscus is included in the family Malvaceae, which comprisesabout 95 genera of herbs, shrubs and trees originating in tropical andtemperate regions. Hibiscus rosa-sinensis is a glabrate shrub, seldomover 8 feet tall in cultivation, but treelike to 15 feet or more intropical regions. Leaves grow to 6-inches in length, and are ovate,usually serrate, mostly glossy green. Flowers are solitary in upper leafaxils.

The new Hibiscus is a product of a planned breeding program conducted bythe Inventor in Webster, Tex. The objective of the program was to createnew Hibiscus selections with improved bloom quality, color andfloriferousness. A further objective was to produce plants that can becommercially produced on their own root systems, with improved planthabit, with regard to vigor and postproduction longevity.

The new variety was discovered in a controlled breeding program ofHibiscus rosa-sinensis and differs from its parents and other knowncultivars of Hibiscus rosa-sinensis by the following characteristics incombination:

1. Upright, compact symmetrical plant habit that is suitable forcontainer production;

2. Healthy dark green foliage;

3. Vigorous growth habit;

4. Large ruffled multicolored flower with a red center, radiating toshades of orange-red with a yellow halo around the edges; and

5. Free flowering.

SUMMARY OF THE INVENTION

The cultivar ‘ISLAND MAGIC’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, light intensity,nutrition and water status without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe unique characteristics of ‘ISLAND MAGIC’. These characteristics incombination distinguish ‘ISLAND MAGIC’ as a new and distinct cultivar:

-   -   1. Upright, compact symmetrical plant habit that is suitable for        container production    -   2. Healthy dark green foliage.    -   3. Vigorous growth habit.    -   4. Large ruffled multicolored flower with a red center,        radiating to shades of orange-red with a yellow halo around the        edges.    -   5. Free flowering.

Asexual reproduction of the new variety by stem cuttings, performed inWebster, Tex. and Houston, Tex., have confirmed that the distinctivecharacteristics of the new variety are stable and transmitted tosucceeding generations, and the new variety reproduces true to type.

COMPARISON WITH PARENTS AND OTHER CULTIVARS

‘ISLAND MAGIC’ is distinguished from its female parent ‘HeartbreakHotel’ (not patented) by its flower color and size. The flower color of‘Heartbreak Hotel’ is mahogany red with yellow spots, and the size ofthe flower is often 2 to 5 cm smaller in diameter than that of ‘ISLANDMAGIC’. ‘ISLAND MAGIC’ is distinguished from its male parent ‘JasonBlue’ (not patented) in the flower color, ‘Jason Blue’ having anorange-yellow flower with a silvery blue eye.

The closest commercial cultivar to ‘ISLAND MAGIC’ known to the Inventoris ‘Orange Magic’ (not patented). However, in side-by-side comparisonsconducted in Webster, Tex., plants of ‘ISLAND MAGIC’ differ from plantsof ‘Orange Magic’ in the following characteristics:

-   -   1. Flowers of the new hibiscus are larger than flowers of the        cultivar ‘Orange Magic’;    -   2. Plants of the new Hibiscus are easier to clone via rooting        than plants of the cultivar ‘Orange Magic’; and    -   3. Plants of the new Hibiscus are more floriferous than are        plants of the cultivar ‘Orange Magic’.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying illustrations show a specimen of the new cultivar in aphotographic illustration as true to color as is reasonably possible tomake in an illustration of this character. Color values in theillustrations may differ slightly from the color values cited in thedetailed botanical description, which accurately describes the actualcolors of the new Hibiscus.

DETAILED DESCRIPTION OF THE INVENTION

‘ISLAND MAGIC’ has not been observed under all possible environmental,cultural and light conditions. The following observations anddescriptions are of plants grown in Fulshear, Tex., in April 2005, underpolypropylene shadecloth providing a 30 percent light reduction, andunder conditions which closely approximate commercial production. Plantsdescribed were approximately one year old.
